Description

本発明は、ビルやマンション等に設けられる扉の両側面の気圧差を解消する扉に関し、特にビル等の排煙装置が動作して扉の両側面の気圧差が非常に大きくなった時に動作する差圧解消装置により、扉の両側面の気圧差を解消させて開き易くする扉に関するものである。   The present invention relates to a door that eliminates a pressure difference between both sides of a door provided in a building, a condominium, etc., and particularly operates when a smoke exhaust device of a building or the like operates and a pressure difference between both sides of the door becomes very large. The present invention relates to a door that can be easily opened by eliminating the pressure difference between both side surfaces of the door by the differential pressure canceling device.

従来より、ビルやマンション等においては、気密性や防音性を高める要求があるために扉の枠にシールパッキン等によるシール構造が提案されている(例えば、特許文献1)。   2. Description of the Related Art Conventionally, in buildings and condominiums and the like, since there is a demand for improving airtightness and soundproofing, a seal structure using a seal packing or the like has been proposed for a door frame (for example, Patent Document 1).

ところが、気密性や防音性の高くなったビルやマンション等においては、火災時に作動する排煙装置によって扉の内側と外側に非常に大きな気圧差が生じ、開扉するとき扉に突然引っ張られたり、扉の開放が不可能になったりする問題が発生する。
上記の問題を解決するために、室内外の気圧差を解消する扉の差圧解消装置については、各種の差圧解消装置が提案されている。
However, in buildings and condominiums with high airtightness and soundproofing, a very large pressure difference occurs between the inside and outside of the door due to the smoke exhaust device that operates in the event of a fire, and the door is suddenly pulled when it opens. The problem that the door cannot be opened occurs.
In order to solve the above problems, various differential pressure eliminating devices have been proposed for the door differential pressure eliminating device that eliminates the atmospheric pressure difference between the inside and outside of the room.

例えば、特許文献2には、室内と室外とを仕切る仕切部材(例えば、出入りのためのドア)には、室内と室外とを連通する空間部を形成しておき、その内側開口部は内側蓋部材によって開閉可能に構成し、外側開口部は外側蓋部材によって開閉可能に構成し、内側蓋部材と外側蓋部材とは連結部材を介して連動するように構成し、内側蓋部材を扉の厚み内に押し込めるという簡単な操作で、外側蓋部材も移動し、両方の内側開口部、外側開口部が開口されて室内外の差圧が解消されるという差圧解消装置が記載されている。   For example, in Patent Document 2, a partition member (for example, a door for entering and exiting) that separates the room from the outside is formed with a space portion that communicates the room and the outside, and the inner opening of the inner cover is an inner lid. It is configured to be openable / closable by a member, the outer opening is configured to be openable / closable by an outer lid member, the inner lid member and the outer lid member are configured to be linked via a connecting member, and the inner lid member is configured to have a thickness of the door. A differential pressure canceling device is described in which the outer lid member is also moved by a simple operation of being pushed in, and both the inner opening portion and the outer opening portion are opened so that the differential pressure inside and outside the room is eliminated.

しかしながら、上記特許文献2の差圧解消装置の構成によれば、室内と室外の差圧を解消するための部材として、主として室内と室外とを連通する空間部のそれぞれの開口部を閉塞する内側蓋部材、外側蓋部材、両者を連結する連結部材、それぞれの蓋部材を押圧して開口部を閉塞する複数のバネ部材で構成されるため部品点数が多く組立工数を含むコスト高と信頼性低下という問題がある。
又、扉の厚み内の対向する面にそれぞれ内側蓋部材、外側蓋部材、連結部材、複数のバネ部材をそれぞれ組み付けることはできないという問題もある。ユニット化して扉の厚み内の片面に取り付ける方法もあるが部品点数が増加してしまうという問題がある。
又、差圧を解消するためにどちらかの蓋部材を扉の厚み内に押し込めるのであるが、内側蓋部材、外側蓋部材、連結部材が連結されているために差圧が解消するまで押し込んでいなければならないという問題もある。
そして、内側蓋部材、外側蓋部材、連結部材が連結されているために、例えば、内側蓋部材を扉の厚み内に押し込めたとき、扉の厚み内に流入した差圧が外側蓋部材を外側開口部側に押圧することにより内側蓋部材の動作が重くなって外側開口部側が所望する開口にならないため、特に差圧が大きい場合(排煙装置が作動した時等)には差圧の解消ができないという問題もある。
However, according to the configuration of the differential pressure canceling device of Patent Document 2, the inner side that mainly closes the respective openings of the space that communicates between the indoor and the outdoor as a member for canceling the differential pressure between the indoor and the outdoor. It is composed of a lid member, an outer lid member, a connecting member that couples the two, and a plurality of spring members that press the respective lid members to close the opening. There is a problem.
There is also a problem that the inner lid member, the outer lid member, the connecting member, and the plurality of spring members cannot be assembled to the opposing surfaces within the thickness of the door, respectively. There is a method of unitizing and attaching to one side within the thickness of the door, but there is a problem that the number of parts increases.
In order to eliminate the differential pressure, either lid member is pushed into the thickness of the door, but the inner lid member, the outer lid member, and the connecting member are connected so that they are pushed in until the differential pressure is eliminated. There is also the problem of having to be.
Since the inner lid member, the outer lid member, and the connecting member are connected, for example, when the inner lid member is pushed into the thickness of the door, the differential pressure that flows into the thickness of the door causes the outer lid member to move outward. The pressure on the opening side increases the operation of the inner lid member and the outer opening side does not have the desired opening, so the differential pressure is eliminated especially when the differential pressure is large (such as when the smoke evacuator is activated). There is also a problem that cannot be done.

本発明は上述の問題点を解消するためになされたものであり、扉に設けられる差圧解消装置に対し、扉の第1表面と第2表面を連通する通気部を設け、通気部内で揺動して通気部の開閉を行なう遮蔽板を備え、扉の第1表面側と第2表面側に気圧差が発生すると気圧の高い方から低い方に風圧が発生するので、この風圧を利用して遮蔽板を揺動させて通気部を開き、扉の第1表面側と第2表面側の気圧差が無くなると遮蔽板の自重により通気部を閉じる構成にすることにより、差圧を解消する部材は、通気部の遮蔽板取付部に装着されて風圧で揺動する遮蔽板のみであり、そのため遮蔽板を揺動させる部材を必要としないので組立やすく、その上、部品点数を最小限にできることにより、部品費の低減と組立工数の低減、更に、信頼性の向上を実現可能にすると共に、風圧があれば遮蔽板を押圧して確実に通気部を開き、風圧がなければ遮蔽板の自重により確実に通気部を閉じるようにして人の力を使用せず自動的に差圧を解消することができる差圧解消装置付扉の提供を目的とする。   The present invention has been made to solve the above-described problems, and a ventilation portion that communicates the first surface and the second surface of the door is provided to the differential pressure elimination device provided in the door, and the shaking is performed in the ventilation portion. It is equipped with a shielding plate that moves and opens and closes the ventilation part. If a pressure difference occurs between the first surface side and the second surface side of the door, wind pressure is generated from higher to lower pressure. By swinging the shielding plate to open the ventilation portion, the pressure difference is eliminated by making the ventilation portion close by the dead weight of the shielding plate when the pressure difference between the first surface side and the second surface side of the door disappears. The member is only a shield plate that is attached to the shield plate mounting portion of the ventilation portion and swings by wind pressure. Therefore, a member that swings the shield plate is not required, so that the assembly is easy and the number of parts is minimized. By being able to reduce the cost of parts, reduce the number of assembly steps, and improve the reliability If there is wind pressure, the shielding plate is pressed to open the ventilation section reliably, and if there is no wind pressure, the ventilation section is reliably closed by the weight of the shielding board and automatically used without human power. An object of the present invention is to provide a door with a differential pressure eliminating device that can eliminate the differential pressure.

次に、請求項2に係る扉によれば、遮蔽板には風圧受け部が設けられている。
遮蔽板は、扉の第1表面側と第2表面側に気圧差が発生すると気圧の高い第1表面側から低い第2表面側に風圧が発生するので、この風圧を受けて第1支持部と第2支持部を中心に第2貫通孔側に回動する。
そのため、風圧受け部を設けることにより、風圧が表面をすべる平面の遮蔽板よりも効率的に風圧を受けて、よりよく遮蔽板を回動させることができる。
Next, according to the door which concerns on Claim 2, the windshield receiving part is provided in the shielding board.
When the pressure difference occurs between the first surface side and the second surface side of the door, the shielding plate generates wind pressure from the first surface side having a high pressure to the second surface side having a low pressure. And the second support portion pivots toward the second through hole side.
For this reason, by providing the wind pressure receiving portion, the wind pressure can be received more efficiently than the flat shielding plate on which the wind slides, and the shielding plate can be rotated better.

次に、請求項3に係る扉によれば、通気部には、第1保持部を有する第1側壁と第2保持部を有する第2側壁を備えると共に通気部をなす上側の第3側壁と下側の第4側壁を備え、遮蔽板の第1支持部を第1側壁の第1保持部に回動可能に装着し、遮蔽板の第2支持部を第2側壁の第2保持部に回動可能に装着すると共に、第3側壁と第4側壁を取り付けて差圧解消ユニットとし、扉の厚みの中に組み込む構成になっている。

このユニット化された差圧解消ユニットにより、ユニットの組み立ても簡単に行うことができ、薄い扉の厚み内への組み込みも簡単になり、メンテナンス及びメンテナンスのための取り外しも簡単に行うことができる。
Next, according to the door according to claim 3, the ventilation portion includes the first side wall having the first holding portion and the second side wall having the second holding portion, and the upper third side wall forming the ventilation portion. A lower fourth side wall is provided, the first support portion of the shielding plate is rotatably attached to the first holding portion of the first side wall, and the second support portion of the shielding plate is attached to the second holding portion of the second side wall. In addition to being rotatably mounted, the third side wall and the fourth side wall are attached to form a differential pressure canceling unit, which is incorporated into the thickness of the door.
With this configuration, the member that eliminates the differential pressure is such that the first support part and the second support part of the shielding plate are provided on the first holding part and the second holding part provided on the first side wall and the second side wall of the ventilation part. There are only a shielding plate that is mounted and rocks by wind pressure, and an upper third side wall and a lower fourth side wall that form a ventilation portion, and it is not necessary to connect to other members to rock the shielding plate. The unit can be formed with a simple configuration of only the ventilation portion and the shielding plate.
This unitized differential pressure canceling unit makes it possible to easily assemble the unit, to easily incorporate it into the thickness of a thin door, and to easily perform maintenance and removal for maintenance.

そして、請求項に係る扉によれば、遮蔽板を扉の厚みの内部で押圧する押圧部材と、押圧部材による遮蔽板の押圧開始と押圧解除を操作する扉の表面に設けられた操作部材と、を備え、遮蔽板が自重により通気部を遮蔽している状態の時に、操作部材が操作されて遮蔽板を押圧部材によって押圧すると共に、扉の両側面における気圧差の発生時に操作部材が操作されて押圧部材による遮蔽板の押圧を解除し、気圧差によって発生する風圧で遮蔽板を回動して通気部を開放する構成になっている。
遮蔽板は、扉の第1表面側と第2表面側に気圧差が発生すると気圧の高い第1表面側から低い第2表面側に風圧が発生するので、この風圧を受けて第1支持部と第2支持部を中心に第2貫通孔側に自動的に回動して常に差圧を解消することができる。
しかし、扉の気密性を保持したい場合には、操作部材を操作して遮蔽板を押圧部材によって扉の厚みの内部で押圧して気密を保持することができると共に、扉の内外の差圧を解消したい場合は、操作部材を操作して遮蔽板を押圧部材から開放することにより、差圧の風圧によって一気に遮蔽板が開き差圧を解消することができる。
即ち、操作部材と押圧部材によって、差圧を簡単にコントロールすることができる。

It is configured to release the ventilation portion by being operated and releasing the pressing of the shielding plate by the pressing member, and rotating the shielding plate with the wind pressure generated by the atmospheric pressure difference.
When the pressure difference occurs between the first surface side and the second surface side of the door, the shielding plate generates wind pressure from the first surface side having a high pressure to the second surface side having a low pressure. Thus, the differential pressure can always be eliminated by automatically rotating around the second support portion toward the second through hole.
However, when it is desired to maintain the airtightness of the door, the operating member can be operated and the shielding plate can be pressed by the pressing member inside the thickness of the door to maintain the airtightness, and the pressure difference between the inside and outside of the door can be maintained. When it is desired to eliminate, by operating the operating member to release the shielding plate from the pressing member, the shielding plate can be opened at once by the wind pressure of the differential pressure to eliminate the differential pressure.
That is, the differential pressure can be easily controlled by the operation member and the pressing member.

In addition, the first mounting guide groove 57a communicating with the first holding portion 48 extends to the upper left when the first support portion 49 of the shielding plate 36 is mounted from the first mounting port 57b. This is because the weight of 36 automatically attaches to the first holding portion 48 through the first attachment guide groove 57a.
Furthermore, it is for preventing the 1st support part 49 of the shielding board 36 from removing from the 1st holding | maintenance part 48, when using as the door 2. As shown in FIG.

同様に、図12の部分正面図に示すように、第2側壁部材32bが第2補強部材23に第2ネジ28によってネジ締めされて取り付けられている。

又、第2保持部50と連通する第2装着案内溝58aが左上方に延伸しているのは、遮蔽板36の第2支持部51が第2装着口58bから装着されたとき、遮蔽板36の自重により、第2装着案内溝58aを通って第2保持部50に自動的に装着させるためである。
さらに、扉2として使用しているときに、第2保持部50から遮蔽板36の第2支持部51が外れないようにするためである。
Similarly, as shown in the partial front view of FIG. 12, the second side wall member 32 b is attached to the second reinforcing member 23 by being screwed with a second screw 28.
A second protrusion 32c is provided on the second side wall 32a of the second side wall member 32b, and a second holding part 50 is perforated on the second side wall 32a forming the side wall of the second protrusion 32c. Yes.

The size of the second mounting opening 58b is formed longer than the length of the second support portion 51 of the shielding plate 36, as shown in the partial front view of FIG.
Further, the second mounting guide groove 58a communicating with the second holding portion 50 extends to the upper left when the second support portion 51 of the shielding plate 36 is mounted from the second mounting port 58b. This is because the weight of 36 automatically attaches to the second holding portion 50 through the second attachment guide groove 58a.
Furthermore, it is for preventing the 2nd support part 51 of the shielding board 36 from removing from the 2nd holding | maintenance part 50, when using as the door 2. As shown in FIG.

この方式によれば、遮蔽板36の第1支持部49と第2支持部51をいつでも第1保持部48と第2保持部50に装着できるので、先に、差圧解消ユニット27としてユニットを作成して扉2に装着する作業にするか、又、それぞれの部材を扉2の厚みの中に取り付けてから遮蔽板36を取り付ける作業するかをその場に合わせた作業を選択することができる。
例えば、差圧解消ユニット27を作成する作業を選択した場合は、遮蔽板36を除いてユニット化しておき、固定化された第1側壁31aに形成された第1突出部31cの側壁をなす第1側壁31aの第1保持部48と、第2側壁32aに形成された第2突出部32cの側壁をなす第2側壁32aの第2保持部50に対し、遮蔽板36の第1支持部49と第2支持部51をこの第1装着案内溝57aと第2装着案内溝58aを経由して組み込むことにより、簡単に遮蔽板36が組み込まれた差圧解消ユニット27を完成させることができる。

According to this method, the first support portion 49 and the second support portion 51 of the shielding plate 36 can be mounted on the first holding portion 48 and the second holding portion 50 at any time. It is possible to select an operation according to the situation whether to create and attach to the door 2 or to attach the shielding plate 36 after attaching each member within the thickness of the door 2. .
For example, when the operation of creating the differential pressure elimination unit 27 is selected, the first plate 31 is formed as a unit excluding the shielding plate 36, and forms the side wall of the first protrusion 31c formed on the fixed first side wall 31a. The first support portion 49 of the shielding plate 36 with respect to the first holding portion 48 of the first side wall 31a and the second holding portion 50 of the second side wall 32a that forms the side wall of the second protrusion 32c formed on the second side wall 32a.

Further, the shielding plate 36 can be easily removed for maintenance.

次に、図6、図7、図13乃至図15に基づいて、差圧解消装置付扉1の動作を説明する。
扉2の第1表面3と第2表面11に発生する差圧を解消するために、図6、図7に示す第1貫通孔7と、第1側壁31aと、第2側壁32aと、第3側壁A33a及び第3側壁B40aと、第4側壁34aと、第2貫通孔19との組合せで形成される通気部47が使用される。
この通気部47に、通気部47の遮蔽・開口をおこなう遮蔽板36を第1貫通孔7の近傍に取り付ける。
遮蔽板36は、遮蔽板36の第1支持部49が第1側壁31aに形成された第1突出部31cの側壁をなす第1側壁31aの第1保持部48に回動支持され、遮蔽板36の第2支持部51が第2側壁32aに形成された第2突出部32cの側壁をなす第2側壁32aの第2保持部50に回動支持される。
これにより、遮蔽板36は、自由に揺動することができる。
遮蔽板36を揺動させる原動力は、差圧によって発生する風圧である。
Next, based on FIG. 6, FIG. 7, FIG. 13 thru | or FIG.
In order to eliminate the differential pressure generated on the first surface 3 and the second surface 11 of the door 2, the first through hole 7, the first side wall 31a, the second side wall 32a, and the second side shown in FIGS. A ventilation portion 47 formed by a combination of the third side wall A33a and the third side wall B40a, the fourth side wall 34a, and the second through hole 19 is used.
A shielding plate 36 that shields and opens the ventilation portion 47 is attached to the ventilation portion 47 in the vicinity of the first through hole 7.
The shielding plate 36 is pivotally supported by the first holding portion 48 of the first side wall 31a in which the first support portion 49 of the shielding plate 36 forms the side wall of the first protruding portion 31c formed on the first side wall 31a. The 36 second support portions 51 are rotatably supported by the second holding portion 50 of the second side wall 32a that forms the side wall of the second protrusion 32c formed on the second side wall 32a.
Thereby, the shielding board 36 can rock | fluctuate freely.
The driving force for swinging the shielding plate 36 is the wind pressure generated by the differential pressure.

そこで、図6に基づいて、遮蔽板36の動作を説明する。
図6に示すように、扉2の第1表面3側と第2表面11側の間に差圧がない場合には、遮蔽板36は自重によって図の実線で示すように垂直になっており、扉2を密閉状態にしている。
そして、扉2の第1表面3側の気圧が高くなり、第2表面11側の気圧が低くなる差圧が発生した場合(例えば、第2表面11側で排煙装置が働いて空気が引かれた時)には、遮蔽板36が高気圧側から低気圧側に発生する風圧Wによって揺動し、図の点線で示すように第2表面11側に開いた状態になる。
更に、図6の切出図に示すように、遮蔽板36に風圧受け部55を設けることにより、より効率的に遮蔽板36を揺動させることができる。
ここで発生する差圧が大きい場合には、通気部47と遮蔽板36が無い通常の扉では扉が開かないという事態になるのであるが、このように、通気部47と遮蔽板36を設けることにより、差圧が解消されて差圧解消装置付扉1の扉2の開閉を簡単におこなうことができるようになるのである。
差圧が解消されると遮蔽板36は、自重で元の位置に戻る。
Therefore, the operation of the shielding plate 36 will be described with reference to FIG.
As shown in FIG. 6, when there is no differential pressure between the first surface 3 side and the second surface 11 side of the door 2, the shielding plate 36 is vertical as shown by the solid line in the figure due to its own weight. The door 2 is sealed.
Then, when a differential pressure is generated in which the air pressure on the first surface 3 side of the door 2 increases and the air pressure on the second surface 11 side decreases (for example, the smoke exhaust device works on the second surface 11 side to draw air). The shielding plate 36 is swung by the wind pressure W generated from the high pressure side to the low pressure side, and is opened to the second surface 11 side as indicated by the dotted line in the figure.
Furthermore, as shown in the cut out view of FIG. 6, the shielding plate 36 can be more efficiently swung by providing the shielding plate 36 with the wind pressure receiving portion 55.
If the differential pressure generated here is large, a normal door without the ventilation part 47 and the shielding plate 36 will not open the door. In this way, the ventilation part 47 and the shielding plate 36 are provided. Thus, the differential pressure is eliminated, and the door 2 of the door 1 with the differential pressure elimination device can be easily opened and closed.
When the differential pressure is eliminated, the shielding plate 36 returns to its original position by its own weight.

このように、図6のみの構成であれば、差圧が発生する度に遮蔽板36が揺動して差圧を解消することになる。
しかしながら、現在の扉は、室外の騒音が入り込まないように、或いは、室内の騒音が漏れないようにするために、気密が保たれているのが一般的である。
そのために、差圧を解消する機構を取り付けた差圧解消装置付扉1に対し、扉2を閉じた状態では、差圧をコントロールせずに気密を保持し、扉2を開く場合に差圧をコントロールする必要がある。
そこで、この差圧解消装置付扉1には、扉2を開くときに、第1蓋部材17に取り付けた差圧をコントロールするためのトリガ用の平面ハンドル錠18と、遮蔽板36を押圧部材37と、平面ハンドル錠18と押圧部材37を連結する可動継手38との組合せが設けられている。
As described above, with the configuration of FIG. 6 only, the shielding plate 36 is swung every time the differential pressure is generated, thereby eliminating the differential pressure.
However, current doors are generally kept airtight so that outdoor noise does not enter or indoor noise does not leak.
For this reason, when the door 2 is closed with respect to the door 1 with a differential pressure canceling device to which a mechanism for canceling the differential pressure is attached, the differential pressure is maintained when the door 2 is opened without controlling the differential pressure. Need to control.
Therefore, the door 1 with the differential pressure canceling device is provided with a trigger flat handle lock 18 for controlling the differential pressure attached to the first lid member 17 and the shielding plate 36 when the door 2 is opened. 37 and a combination of a movable joint 38 that connects the flat handle lock 18 and the pressing member 37 are provided.

その動作と関係を図13に基づいて説明する。
先ず、図13の図Gに示すように、平面ハンドル錠18をロックすると、可動継手38が水平になり、押圧部材37(実線)を垂直のまま右斜め上方に移動した状態にする。
平面ハンドル錠18のロックを解除すると、可動継手38が右下方に傾斜し、押圧部材37(点線)を垂直のまま左斜め下方に移動した状態にする。
この時の押圧部材37の平面ハンドル錠18側へ移動した距離は移動距離Lである。
この移動距離Lにより、押圧部材37が右斜め上方にあるときは、押圧部材37の位置が遮蔽板36を覆う位置になるように設定し、押圧部材37が遮蔽板36を押圧するように設定している。
押圧部材37が左斜め下方にあるときは、押圧部材37が遮蔽板36を開放する位置になるように設定している。
The operation and relationship will be described with reference to FIG.
First, as shown in FIG. G of FIG. 13, when the flat handle lock 18 is locked, the movable joint 38 becomes horizontal, and the pressing member 37 (solid line) is moved upward and diagonally to the right.
When the lock of the flat handle lock 18 is released, the movable joint 38 is inclined to the lower right, and the pressing member 37 (dotted line) is moved obliquely to the left and left downward.
The distance moved to the flat handle lock 18 side of the pressing member 37 at this time is the moving distance L.
With this moving distance L, when the pressing member 37 is obliquely upward to the right, the pressing member 37 is set so that the position of the pressing member 37 covers the shielding plate 36, and the pressing member 37 presses the shielding plate 36. doing.
When the pressing member 37 is diagonally downward to the left, the pressing member 37 is set to a position where the shielding plate 36 is opened.

この押圧部材37と遮蔽板36の動作と関係を図7、図13乃至図15に基づいて説明する。
図7と図13の図Hでは、平面ハンドル錠18がロックされ、遮蔽板36が押圧部材37によって押圧されている。
この状態であれば、扉2の気密は保たれ、扉2の内外の騒音には影響されない。
しかし、扉2の第1表面3側の気圧が高く、扉2の第2表面11側の気圧が低くなった状態のときには、扉2を開くのが困難な状態になる。
特に、扉2の第2表面11側で排煙装置が作動すると、扉2が開かないという事態が発生する事もある。
そこで、図13の図Jと図14で示すように、平面ハンドル錠18のロックを解除すると、押圧部材37が移動距離Lだけ図の平面ハンドル錠18側に移動し、遮蔽板36の押圧を解除した状態になる。
しかし、扉2の第1表面3側と第2表面11側とに差圧があるために、直ちに、図13の図Kと図15で示すように、遮蔽板36が高気圧側から低気圧側に発生する風圧Wによって揺動し、第2表面11側に開いて差圧を解消する。
これにより、扉2を通常どおりに開くことができる。
そして、差圧が解消されると遮蔽板36は、自重で元の位置に戻る。
The operation and relationship between the pressing member 37 and the shielding plate 36 will be described with reference to FIGS. 7 and 13 to 15.
7 and 13, the flat handle lock 18 is locked, and the shielding plate 36 is pressed by the pressing member 37.
In this state, the airtightness of the door 2 is maintained, and it is not affected by the noise inside and outside the door 2.
However, when the pressure on the first surface 3 side of the door 2 is high and the pressure on the second surface 11 side of the door 2 is low, it is difficult to open the door 2.
In particular, when the smoke evacuation device is activated on the second surface 11 side of the door 2, the door 2 may not be opened.
Therefore, as shown in FIGS. 13 and 14 in FIG. 13, when the flat handle lock 18 is unlocked, the pressing member 37 moves toward the flat handle lock 18 in the drawing by the moving distance L, and the shielding plate 36 is pressed. It will be in a released state.
However, since there is a differential pressure between the first surface 3 side and the second surface 11 side of the door 2, as shown in FIG. 13 and FIG. Oscillates due to the wind pressure W generated at the second, and opens to the second surface 11 side to eliminate the differential pressure.
Thereby, the door 2 can be opened as usual.
When the differential pressure is eliminated, the shielding plate 36 returns to its original position with its own weight.

以上説明したように、本実施形態に係る扉2によれば、扉2の両側面において発生する空気の気圧差を解消する扉2であって、扉2の気圧が高くなる側の第1表面3を構成する第1板部材5に設けられた第1貫通孔7と、扉2にて第1表面3と対向し、気圧が相対的に低くなる側の第2表面11を構成する第2板部材13に設けられた第2貫通孔19と、扉2の第1板部材5と第2板部材13の間で、第1貫通孔7と第2貫通孔19を連通し、第1表面3側の空気を第2表面11側に通過させる通気部47と、通気部47の第1貫通孔7側の第1側壁31aに設けられた第1保持部48と、通気部47にて第1保持部48と対向する第1貫通孔7側の第2側壁32aに設けられた第2保持部50と、上端部に、第1保持部48に回動係止される第1支持部49と第2保持部50に回動係止される第2支持部51を有し通気部47を遮蔽する遮蔽板36と、を備え、遮蔽板36は、第1表面3側の高くなった気圧と第2表面11側の相対的に低い気圧との差によって発生する第1貫通孔7から第2貫通孔19側への風圧により、第1支持部49と第2支持部51を中心に第2貫通孔19側に回動し、通気部47を開放して第1表面3側と第2表面11側の気圧差を解消すると共に、第1表面3側と第2表面11側の気圧差が無くなると遮蔽板36の自重により第1支持部49と第2支持部51を中心に回動して通気部47を遮蔽するようにする構成になっている。   As described above, according to the door 2 according to the present embodiment, the door 2 eliminates the air pressure difference generated on both side surfaces of the door 2, and the first surface on the side where the air pressure of the door 2 is increased. The first through-hole 7 provided in the first plate member 5 constituting 3 and the second surface 11 facing the first surface 3 at the door 2 and constituting the second surface 11 on the side where the atmospheric pressure becomes relatively low. The first through hole 7 and the second through hole 19 communicate with each other between the second through hole 19 provided in the plate member 13 and the first plate member 5 and the second plate member 13 of the door 2, and the first surface. The ventilation part 47 that allows the air on the third side to pass to the second surface 11 side, the first holding part 48 provided on the first side wall 31a on the first through hole 7 side of the ventilation part 47, and the ventilation part 47 The second holding portion 50 provided on the second side wall 32a on the first through hole 7 side facing the first holding portion 48 and the upper end portion are pivotally locked to the first holding portion 48. A shield plate 36 having a second support portion 51 that is pivotally locked to the first support portion 49 and the second holding portion 50 and shielding the ventilation portion 47. The shield plate 36 is on the first surface 3 side. The first support portion 49 and the second support portion are caused by the wind pressure from the first through hole 7 to the second through hole 19 side generated by the difference between the increased atmospheric pressure and the relatively low atmospheric pressure on the second surface 11 side. 51, the second through hole 19 is rotated around 51, the vent 47 is opened to eliminate the pressure difference between the first surface 3 side and the second surface 11 side, and the first surface 3 side and the second surface. When the pressure difference on the 11th side is eliminated, the ventilation plate 47 is shielded by rotating around the first support portion 49 and the second support portion 51 by the weight of the shielding plate 36.

この構成によれば、扉2の第1表面3側と第2表面11側に気圧差が発生すると気圧の高い第1表面3側から低い第2表面11側に風圧が発生するので、この風圧を利用して通気部47内に取付けられた遮蔽板36を第1支持部49と第2支持部51を中心に第2貫通孔19側に回動し、通気部47を開放して第1表面3側と第2表面11側の気圧差を解消することができる。
又、遮蔽板36は、風圧が無い場合は自重により、自動的に元の位置に戻って通気部47を遮蔽することができる。
このように風圧の有無によって遮蔽板36を開閉させるので、通気部47の開閉を行なうために人力によって遮蔽板36を回動するような伝達部材を無くすことができる。
According to this configuration, when a pressure difference occurs between the first surface 3 side and the second surface 11 side of the door 2, wind pressure is generated from the first surface 3 side having a high pressure to the second surface 11 side having a low pressure. The shielding plate 36 attached in the ventilation part 47 is rotated around the first support part 49 and the second support part 51 to the second through-hole 19 side by using the first and second ventilation parts 47 to open the first ventilation part 47. The pressure difference between the surface 3 side and the second surface 11 side can be eliminated.
Further, when there is no wind pressure, the shielding plate 36 can automatically return to its original position and shield the ventilation portion 47 by its own weight.
Thus, since the shielding plate 36 is opened / closed depending on the presence / absence of the wind pressure, it is possible to eliminate a transmission member that manually rotates the shielding plate 36 in order to open / close the ventilation portion 47.

即ち、差圧を解消する部材は、通気部47内で第1保持部48と第2保持部50に装着されて風圧よって揺動する遮蔽板36のみであり、遮蔽板36を揺動させる部材を必要としないために組立やすく、その上、部品点数を最小限にできるので、部品費の低減と組立工数の低減、更に、信頼性の向上を実現可能にすると共に、風圧があれば遮蔽板36を押圧して確実に通気部47を開き、風圧がなければ遮蔽板36の自重により確実に通気部47を閉じるようにして人の力を使用せず自動的に差圧を解消することができる。   That is, the member that eliminates the differential pressure is only the shielding plate 36 that is attached to the first holding portion 48 and the second holding portion 50 in the ventilation portion 47 and swings by the wind pressure, and the member that swings the shielding plate 36. It is easy to assemble because it does not require a large number of parts, and the number of parts can be minimized, so that it is possible to reduce the parts cost, reduce the number of assembly steps, and improve the reliability. 36 is pressed to reliably open the ventilation portion 47, and if there is no wind pressure, the ventilation portion 47 is reliably closed by the weight of the shielding plate 36 so that the pressure difference is automatically eliminated without using human force. it can.

次に、扉2によれば、遮蔽板36には風圧受け部55が設けられている。
遮蔽板36は、扉2の第1表面3側と第2表面11側に気圧差が発生すると気圧の高い第1表面3側から低い第2表面11側に風圧が発生するので、この風圧を受けて第1支持部49と第2支持部51を中心に第2貫通孔19側に回動する。
そのため、風圧受け部55を設けることにより、風圧が表面をすべる平面の遮蔽板36よりも効率的に風圧を受けて、よりよく遮蔽板36を回動させることができる。
Next, according to the door 2, a wind pressure receiving portion 55 is provided on the shielding plate 36.
The shielding plate 36 generates a wind pressure from the first surface 3 side having a high pressure to the second surface 11 side having a low pressure when a pressure difference occurs between the first surface 3 side and the second surface 11 side of the door 2. Upon receipt, the first support part 49 and the second support part 51 are rotated around the second through hole 19 side.
Therefore, by providing the wind pressure receiving portion 55, the wind pressure can be received more efficiently than the flat shield plate 36 on which the surface slides, and the shield plate 36 can be rotated better.

次に、扉2によれば、通気部47には、第1保持部48を有する第1側壁31aと第2保持部50を有する第2側壁32aを備えると共に通気部47をなす上側の第3側壁A33a及び第3側壁B40aと下側の第4側壁34aを備え、遮蔽板36の第1支持部49を第1側壁31aの第1保持部48に回動可能に装着し、遮蔽板36の第2支持部51を第2側壁32aの第2保持部50に回動可能に装着すると共に、第3側壁A33a及び第3側壁B40aと第4側壁34aを取り付けて差圧解消ユニット27とし、扉2の厚みの中に組み込む構成になっている。
この構成により、差圧を解消する部材は、通気部47の第1側壁31aと第2側壁32aに設けられた第1保持部48と第2保持部50に、遮蔽板36の第1支持部49と第2支持部51が装着されて風圧によって揺動する遮蔽板36と、通気部47をなす上側の第3側壁A33a及び第3側壁B40aと下側の第4側壁34aのみであり、遮蔽板36を揺動するために他の部材と連結する必要が無いので通気部47と遮蔽板36のみの簡単な構成でユニット化することができる。
このユニット化された差圧解消ユニット27により、ユニットの組み立ても簡単に行うことができ、薄い扉2の厚み内への組み込みも簡単になり、メンテナンス及びメンテナンスのための取り外しも簡単に行うことができる。
Next, according to the door 2, the ventilation part 47 includes the first side wall 31 a having the first holding part 48 and the second side wall 32 a having the second holding part 50, and the upper third side forming the ventilation part 47.
